I breathe in my arms and live a new life. My body is more developed for the upper body than the lower body, so my arms were especially stressful. That 's why it's normal that I ca n't wear a shirt in the summer. I'm envious.. I used to do it with my forearm and rich room, but now I wear it with confidence!!! I am very satisfied with this alone! There are no scars, maybe because it's been a long time, so I couldn't see it well at first, but there's nothing bumpy, and even after a long time, my forearms are the same .
